You are given the root
of a full binary tree with the following properties:
0
or 1
, where 0
represents False
and 1
represents True
.2
or 3
, where 2
represents the boolean OR
and 3
represents the boolean AND
.The evaluation of a node is as follows:
True
or False
.Return the boolean result of evaluating the root
node.
A full binary tree is a binary tree where each node has either 0
or 2
children.
A leaf node is a node that has zero children.
Example 1:
Input: root = [2,1,3,null,null,0,1] Output: true Explanation: The above diagram illustrates the evaluation process. The AND node evaluates to False AND True = False. The OR node evaluates to True OR False = True. The root node evaluates to True, so we return true.
Example 2:
Input: root = [0] Output: false Explanation: The root node is a leaf node and it evaluates to false, so we return false.
